3.7v 1800mAh Battery Replacement for Corsair HS70,HS75 XB, Void Pro RGB Headset, HyperX Cloud III/Cloud II Headset

I used this battery as a replacement for a faulty Corsair HS70 wireless. Those are now sold as Corsair he wireless pro. I'm quite unsure about the differences between these generations, but one thing is consistent, their awful battery life. The headset would only work for about 6 hours, which is not the time advertised at all (10+ hours). Moreover, the original battery on the headset stopped working after two years with minimal use. I decided to upgrade the battery and got this one. The battery replacement process was slightly tedious since the previous battery was soldered to the main headset chip. The battery is thick, but it still fits. I even used thick double sided tape in order to secure the battery in place. Anyhow, this battery has been working wonderfully for about a week. The headset can easily last about 10 hours or more. I'd definitely recommend this battery. But make sure you have some previous knowledge or watch some YouTube videos before you change the battery.

This battery was quite difficult to install. I dont recomend it unless your ready to spend a half hour fumbling small screws and wrestling with a springy pair of headphones with tiny delicate wire speakers that can rip out. The most difficult part wasn't switching the polarity on the cable, but it was trying to get the new battery to plug into the headphones. It was not a good fit and it was difficult to get the small plug to fit into the slot. After lots of fumbling and dropping things I got it back together. I have to say the battery is working very well. It holds a charge for much longer than the original battery, at least as far as I can remember. I must have used them for over 24 hours without having to recharge them. If your ready for the challenge I recommend this battery can save you $60. Update this battery lasted 9 months. It no longer holds a charge.

Battery in my Corsair Virtuoso RGB SE headphones wouldnt take a charge anymore. This fixed the headphones. The price was totally worth it to keep these expensive headphones going. Replaced the 1200 mah stock battery with this 1800 mah battery so this lasts longer on a charge. This battery is thicker than the stock battery so it is a snug fit when screwing the speaker plate back down, so be careful, but the tension holds the battery in place. The plug wiring was correct and I did not have to swap the black and red wires. We will now see how long this battery lasts.

This does not fit my headset. It states clearly in several places it is compatible with the Corsair VOID RGB; the battery is narrower and thicker than the Corsair VOID RGB battery and does not fit in the space provided in the headphones. Testing also shows this is not 1800 mAh; barely getting half. Do not recommend.

Needed to replace the stock battery in a Corsair HS70 Pro Wireless that was getting less than 2hrs on a full charge. Highly recommend watching YouTube videos on how to replace this before purchasing. Although the headset's battery is replaceable, the process is not user friendly. The stock battery is glued into place so you'll need something to break the adhesive and pry it out. Two wires had to be reversed as shown in the product photos. There are no included instructions so be sure to check the wires before installing. I used a utility knife to pry up the clips holding the wires in the connector. DO NOT let the wires touch. Wrap the connectors in electrical tape while reversing them. The angle of the female connector made this very difficult to reinstall so I had to bend it slightly to get it to fully insert. A bit of super glue got this to hold in place. Left the headset on for 8 hours straight and it wasn't beeping that the battery was low. Very happy getting another few years out of this headset at a fraction of the cost of tossing it for a new one. Great battery that works as advertised.

As with many of the other reviews, I also had to switch the wires to match the correct polarity with my Corsair HS70 Pro. The replacement took about 20 min altogether with most of it fiddling with the wires prior to the actual replacement. The ear cup comes off fine, remove some screws, and then pry up the old battery from the glue/adhesive that was used. Then simply plug in the new one. The new one worked great for about 3 months with about 6-8 hours of charge (I use my headset all day for work). The next 3 months the charge dropped to around 4hrs and I was getting some spotty charging results. Over the last month, it would spontaneously stop charging and I would get to my desk in the morning and it would only last about 15 minutes. Sometimes it would be dead as a doornail. Then sporadically I would get 3-6 hours of charge out of it again. It has gotten so inconsistent that I'll be buying another battery (possibly from another vendor). Still, it is cheaper than replacing the headset altogether.

I can't comment on longevity of this battery, as I just purchased it a few days ago. I bought it to replace the factory battery in my Corsair HS70 Pro Wireless headset and it was a perfect fit. The only thing that might be a pain for some folks to install, is that the positive and negative wiring was reversed with the new battery. It took me five minutes with a letter opener and my magnifying glass light to gently pry the plastic tangs holding the positive and negative wires in the tiny connector of the new battery to swap the position of the two wires. I used some electrical tape to fold and attach the battery to the housing in the headphone case. After getting the headphones back together, I tested turning them on and they powered on fine. I let them charge fully, then used them for hours the next day unplugged. So far, very satisfied with new battery, will see how long it holds up to daily use. Nice to pay $20 to fix versus paying another $100 for a new headset!

This battery is works, but it's low quality and reaches end of life before 1.5 years in use. Purchased this batter Dec 2023. It's May 2025 and this battery is already end of life (losing 80% charge within 30 minutes of use). The original factory battery lasted 8 years before it got this bad. If a replacement part can't exceed the factory default, it's trash. This is a trash battery.

Durata della batteria notevole

I have had a Corsair HS70 which I bought about 3 years ago now for use in work meetings since we had to all go digital during COVID. The original battery however has not lasted and during this year has barely held a charge before finally quitting entirely last month. Corsair does not offer replacement batteries as they list it as hazardous for users to change them, and being out of warranty there was not much I could do. Thanks to Google and some forum searches, I was able to come across this replacement battery which was actually available at Amazon.ca and not just the US .com site. It was really easy to replace, although I did have to swap the positive and negative wires on the battery connector as noted in the product description - and while finnicky and annoying, it was not hard. The battery had less than a 50% charge out of the box but I was able to get well over 8 hours of run time out of it from that state before charging. It also recharges in a reasonable amount of time as one would expect. I am very happy to keep a pricey headset going with even more battery capacity than stock. I was not big on the idea of a wireless headset from the get go due to late-life battery concerns but with replacement this easy, I don't really have a problem with that anymore.

El producto funciona en el dispositivo y tiene unas dimensiones como la original por lo que no hace falta romper el compartimento de cascos Corsair HS70 Pro Wireless para que quepa en los cascos. Una cosa a resaltar es que el orden de los cables esta invertido y se ha de manipular antes de conectar. Fijaros en la distribucion de los cables mirando a los pines para saber que lo introducis correctamente, respecto los cascos originales. El cambio de bateria lo hice pq los cascos ya tienen muchos años y la bateria anterior esta completamente muerta (se puede ver lo bufada que está en la foto). Esta bateria con un ~50% mas de carga espero que aguante por lo menos igual, nohe podido hacer pruebas de la duración, pero de momento parece que todo bien.

I was able to fix my headset Corsair HS70 pro wireless. Life battery is great, lasts longer than the original battery the headset comes with.
